摘　　要：分析了与变电站自动化系统密切相关的新技术的发展与应用对其技术发展趋势的深刻影响。介绍了电子式互感器技术的发展,为保护和控制的集成与新原理保护的研究创造了有利条件;柔性交流输电技术的快速发展和多媒体音频和视频技术及光纤通信在变电站的应用,扩展了变电站自动化系统的安全监控和故障诊断等功能;电力工业运营机制的改革,对变电站自动化系统的功能和可靠性提出了更高的需求。显然,随着新技术的不断涌现和应用,将全面推动变电站自动化系统的功能和结构向全数字化、高度智能化、传输规约和传输网络标准化的方向发展。Based on the analysis of the important influence of the development and applications of some new technologies to substation automation system, this paper proposes the possible tendencies in this field. With the development and application of the electronic instrument transformer technology, the rapid development of flexible alternate current transmission technique and the application of multimedia and the optical fiber communication technologies in the substation, the functions of security monitoring, fault diagnosing and so on in substation automation systems have explicitly expanded. The reform of working mechanism of the electrical power industry raises much more requirements to the functions of substation automation systems. It is obvious that accompanying with the ceaseless emergence and application of new technologies, the functions and system architecture of substation automation system will be promoted to the direction of complete digitization, high level intelligentization, and standardization of transmission protocol and transmission networking.
